LoggerPointAlreadyRegistered

Enumeration name:	LoggerPointAlreadyRegistered
Enumeration value:	36
Description:	Logger point is already registered.

Status message: The logger point of the function block is already registered in the Application Logger.

MaxNumberOfLoggerPointsExeeded

Enumeration name:	MaxNumberOfLoggerPointsExceeded
Enumeration value:	3
Description:	The maximum number of logger points was exceeded.

Issue	Cause	Solution
The maximum number of logger points has been exceeded. Registering the function block as logger point to the Application Logger was not successful.	There are already Gc_udiMaxNumberOfLoggerPoints logger points registered in the Application Logger.	The global parameter Gc_udiMaxNumberOfLoggerPoints has to be set to a greater value to register the logger points of the project.

Issue

Cause

Solution

The maximum number of logger points has been exceeded.

Registering the function block as logger point to the Application Logger was not successful.

There are already Gc_udiMaxNumberOfLoggerPoints logger points registered in the Application Logger.

The global parameter Gc_udiMaxNumberOfLoggerPoints has to be set to a greater value to register the logger points of the project.

Enumeration name:	Ok
Enumeration value:	0
Description:	Ok

Status message: Registration of the function block was successful.

ParentInvalid

Enumeration name:	ParentInvalid
Enumeration value:	1
Description:	The parent is invalid.

Issue	Cause	Solution
The parent is invalid. Registering the function block as logger point to the Application Logger was not successful.	An invalid object was transferred at the input i_ifParent.	Verify that at the input i_ifParent an object of type APL.FB_LoggerPoint or APL.IF_ApplicationLogger is transferred.

ParentNotRegistered

Enumeration name:	ParentNotRegistered
Enumeration value:	2
Description:	The parent is not registered.

Issue	Cause	Solution
The parent is not registered. Registering the function block as logger point to the Application Logger was not successful.	The logger point transferred at the input i_ifParent is not registered in the Application Logger.	The logger point transferred at the input i_ifParent must be registered in the Application Logger first.

ServiceNotRegistered

Enumeration name:	ServiceNotRegistered
Enumeration value:	7
Description:	The service is not registered.

Issue	Cause	Solution
The service is not registered. Registering the function block as logger point to the Application Logger was not successful.	The Application Logger communication service is not registered.	The communication service of the Application Logger has to be registered first. The interface IF_ApplicationLogger.RegisterCommunicationService has to be called successfully once, before a logger point can be registered in the Application Logger.

UnexpectedFeedback

Enumeration name:	UnexpectedFeedback
Enumeration value:	4
Description:	Internal error detected.

Issue	Cause	Solution
Feedback was invalid.	Receiving data was not successful, the server was shut down.	Restart the server.
